The Evolution of Crash Testing and its Impact on Car Safety
TLDR Crash testing has greatly improved car safety over the years, with advancements in technology and the use of realistic crash test dummies. However, as 3D modeling and computer simulations advance, crash test dummies may become less widely used in the future.
Timestamped Summary
00:00
Cars have become exponentially safer due to crash testing, which has led to increased awareness and prioritization of safety in the automotive industry.
05:04
Crash testing began in 1934 with unoccupied vehicles, but it wasn't until 1952 that anthropomorphic dummies were created for testing airplanes and spacecraft, eventually leading to the development of the first crash test dummy for cars in 1981.
10:18
Crash testers are starting to use female crash test dummies, but they still can't replicate tissue or real damage, so they also use postmortem human subjects for some crash testing.
15:55
Crash test dummies are becoming more realistic with simulated internal organs to better replicate human responses during crashes.
21:11
Crash test dummies may not become widely used in the future as 3D modeling and computer simulations are rapidly advancing, allowing for virtual testing of cars based on input parameters and measurements.
26:06
Crash tests involve high-speed cameras, sensors, and visual inspection to capture data that may not be picked up by the sensors, and different types of crashes, such as partial overlaps, are now being tested to improve safety standards.
30:56
Crash testers have demonstrated the need for safety features like seatbelt pretensioners, force limiters, and airbags, leading automakers to respond and improve safety standards.
36:09
Crash tests conducted by the National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety involve various types of impacts, including full frontal crashes and partial bumper crashes, to assess the safety of vehicles and the likelihood of injuries.
41:35
Crash testing standards and criteria have evolved since 2010, with changes including the introduction of new injury parameters, the use of different size dummies, additional measures for neck extension, chest deflection, and femur, and the comparison of cars against one another rather than just against set criteria.
46:19
Crash testing is not mandatory for car makers, but the fact that agencies are conducting their own tests and crashing cars shows that people care about the safety of others, and newer cars with safety features and seatbelts are much safer in standard car crashes.
